Modelling Sandwich panels
Altair EmployeeHI there
I have imported a 3D CAD model to HyperMesh that includes sandwich panels and I would like to ask the best way to mesh these? I have tried using a 3d mesh on the geometry to represent the core properties, and added a 2d mesh to the faces to represent the skin properties (created by using the 'find faces' tool). When I try and solve however, I get multiple 'Error 14: Missing Property # 4 referenced by CQUAD4 # x'
Searching on here, it appears that this is a problem with the 2d mesh on the 3d nesh, so a better way to represent the panels would be appreciated!

Hi,
check if you have applied a PSHELL property to the CQUAD4 element # x. If the element is not compatible with the property it throws this error. Also ensure that different types of elements (shells, solids) are assigned to different components.

Hi dears,
I am doing midal analysis for sandwich with laminated face honeycomb core.
For face Mat8 pcomg 2d
For core mat1 psolid 3d
Find face method
I am getting error message as following
User fatal message 6440 (MODGM2)
Element 2381 Refers to an invalid property entry
User action : spespecify appropriate property entry
Kindly
Suggest where I am going wrong

Hi,
looks like element 2381 is assigned inappropriate property- either shell element is assigned 3D property (PSOLID) or vice versa.

Is my method of modelling is correct??

Some shell elements were assigned to CORE component which had solid propety. After deleting those elements the model is able to run.

I am getting error sir
Let me know where I am getting wrong

Your PSOLID property (ID=2) references to material ID=4 which does not exist.
So check your materials definition.
